[Mod edit:  If you make materials for a specific lesson in your book then start a new thread.  However, this thread has no material...yet.  There are plenty of materials about the weather already on waygook that maybe a thread isn't necessary for this specific lesson/book.]

That is true, but each book has its own nuances, key expressions, etc. so I think an independent thread may be useful.

So here is some material.

A couple ppt's dealing with "Let's go/play _______"

Here's a song about the weather with English and Korean. My students love it and ask me to play it all the time!! I've attached the lyrics as well!
:)

Here's a quick game and review for period 3 role play. I just put together a Word Scramble Game...followed by a review on temperature and weather.

After the PPT, i would go to the book and give the students 10min to practice/memorize their roleplay roles.

The Mario weather game is brilliant. Thank you!

Cut out pictures of different types of clothing and stick a magnet on the back of the pictures. Split the class into two teams and have one person come up to the front for both teams. Then the coteacher will ask you how is the weather today, and then you reply. Whatever you want. When the two students hear this they must grab as many articles of clothing on the board that corresponds to that weather and attach them to the stick person you drew on the board. The person with the most articles of clothing is the winner

Here is a slant on the Mario expressions game but with more going on, along the MARIO WORLD version.  It's good for up to 20 mins

Here's a Kaboom game I made which combines the weather with the Let's play, let's go hiking etc...

Thank you Cameron. You save my life!  I was wondering, do have the instructions to the Mario game?  The game is amazing, but I'm not sure I can explain it to my students.
